【Paraffin Expansion Structure】: The thermostat uses calibrated paraffin filled thermal sensing elements inside. When the coolant temperature rises, the paraffin melts and expands, pushing the piston to open the valve and achieve precise temperature control, opening temperature is 192℉
【Reliable Material】: The thermostat uses a brass shell and guide structure, which helps to quickly conduct heat and improve response efficiency, and use stainless steel piston, spring frame and bridge structure provide higher strength, corrosion resistance, and long-term reliability.
